IMPROVEMENT IN COAL-ELEVATORS.

The Schedule referred to in these Letters Patent and making part of the same I, ALsoN S. BAILEY, of Chicago, inthe county of Cook, and State of Illinois, have invented certa-in Improvements inOoal-Elevators, of which the following is a specification.

My invention relates to a machine for elevating coal from the hold of a vessel, by means of trucks or buckets attached to endless chains and running on inclined trani-ways. The trucks or buckets are jointed transversely, so that Vthey are readily carried 4by the chains in their circuit; and the whole machine is so jointed that the receiving end of the elevator may be placed in the hold of' the vessehfroin which 'the coal is lifted perpendicularly, after which it is carried along airinclue to the place ot deposit, all ofwhich will more fully hereinafter appear.

Description of Accompanying Drawings. v

Figure 1 is a side elevation of my invention. Figure 2 is a plan or top view ot' the saine. Figure 3 is a detached part of fig. 1. Figure 4 is a truck or bucket detached. Figure 5 is a transverse section of some.

General Description.

A B C represent the three jointed parts, which I will terni sections. Section A supported in an inclined position by the frame-work a. To the lower end of section A is jointed Section B, and to the lower end of section B is jointed section C.

Section A consists of two pieces b b, which are part of the frame. `At the upper end'ofthese pieces is the shaft D, carrying the rag-wheels d and the cog-wheel df, whichcog-wheel meshes into a cog-wheel, e, indicated` by the dotted lines in tig. 1. This latter cogwheel e is connected with the pulley E, to which power is applied to run themachine. Ihe rug-Wheels tl carry the endless chains f, two in number, which extend the entire length of the elevator, and pass around the cylirder F, indicated by the dotted lines in in section O o iig. 1.

The said endless chains pass over and are supported by the pulleys G and G', placed one above the other, at the joining of sections A and B, the shaft of the pulleys G forming the pivot of the joint. And the saidendless chains pass over and are supported by other pulleys H and Id', the shaft of the pulley H forming in like manner the pivot of the joint between sections B and O. There are two of each of the abovenamed pulleys, one set for each endless chain, each shaft supporting two pulleys.

I are the trucks or buckets for conveying the coal. Said trucks or buckets are attached, by means of a projection of the axle of their wheels i, to the endless chains, and are carried around by the said chains in their circuits. rIhese trucks or buckets are jointed at about their center transversely, so that theycan pass readily round the rag-wheels d and cylinder F. This joint is clearly shown at i,.fig 5. The back part of these trucks or buckets is made in the shape of a box, with the top and bottom and three sides inclosed, but the front side is opened. To the front edge of the bottom of said box-like part is hinged theother half of the truck or bucket, consisting ot' abottom piece, with two seinicircnlar side pieces 7c, which lap past the sides ofthe above-described box-like part, as clearly shown in tigs. 4 and 5, but are not attached-thereto.

Owing to the arrangement of the pulleys G G and H H', as above described, the sections B and G may be placed at any angle below the line of direction of l section A, and the endless chains will remain parallel;

the sections, and in passing round the cylinder F said wheels run in grooves cut therein. The section G is constructed in the form of a semicylindrical ense, inclosed upon one side and part of the bottom by the casing l, curved to conform to the course of the trucks or buckets. When-the machine is inactual operation the section-` O will hang in a nearly perpendicular direction, as shown in tig. 1. I

Attached to the section O, and projecting to the outer front thereof, is the feeding t pparatus M, consisting of the frame-Work m, in whic is hung the revolving box N, said box being divided longitudinally into four compartments. the dotted lines in fig. 3.

To the shaft which carries said `revolving box isafixed the ratchet-wheel o, with the pawl pattached-to the quadrant q.

Attached to said quadrant is the lever fr, which connects with the lever s', which lever is attached to a fulcrum bearing in the frame-work in, and has at its outer end an idler or friction-pulley, u'. the path of the trucks or buckets, and as they pass is struck by the semicircular .pieces k and the-lever selevated, which turns the box N and dumps the coal, which has been shoveled therein, into the truck or bucket, which has caused the action of the lever as above. After the truck or bucket is thus filled and carried on out of the way, the lever s resumes, by its Said division is indicated by This pulley lies in in handling large or lump-coal. When small coal is handled this apparatus is not necessary, but the trucks 'beneath or behind the course of the trucks or buckets as they come from under the cylinder F. 'lhe oice of this guard-piece will be to prevent-coal from falling from the buckets over behind the cylinder, and thus clogging up the same,

By reason of the joints between the sections the elevator may be adj usted to any depth of hold, andthe motion of a 4vessel at the dock while being unladen, caused by the rise and i'all of the Water, does not interfere in the least with the operation of this elevator. Even a considerable lateral motion will not interfere, so that a vessel may be unladen in a heavysea with comparative ease.

To section B is attached a bale, P, extending from side to side, arched to allow the trucks or buckets t-o pass beneath it. To this bale is aiiixed the'block and tackle lj L, for the purpose of raising and lowering and adjusting theses-tions B and C.

Claims.

I claim as my invention- 1. Theelevator-frame, constructed as shown, with seotions laying at dii'erent angles, so that the elevating buckets are carried more nearly perpendicular on some sections of the frame than on others.

2. The combination 'of tbe sections A, B, and G of the elevator frame, when hinged together, substantially as and for the purposes specilied and shown.

3. The combination of the frame-Work a b, pulley E, cog-wheels e and d', rag-wheels d, endless chains f, pulleys G Gaud H H', section O with its casing l, and the hoisting apparatus P P' L, constructed and oper ating substantially as specified and shown.

4. The combination'of the elevating-truck or bucket I, wheels i, chain and tram-way or track t, substantially as and for the purpose speoiiied.

5. The feeding apparatus M, substantially as and for the purpose speciiied and shown.
